3,302 Possible Causes for EMG Shows Evidence of Reinnervation, Muscle Biopsy Abnormal, Muscular Atrophy

  • Motor Neuron Disease

    For patients with MND affecting the LMNs, the EMG will show evidence of: (1) acute denervation, which is ongoing as motor neurons degenerate, and (2) chronic denervation and[en.wikipedia.org] The results of electromyography and muscle biopsy were compatible with ALS. However, supranuclear vertical gaze palsy and slow saccades are seen.[ncbi.nlm.nih.gov] Some MNDs, such as ALS and some forms of spinal muscular atrophy, are fatal.[ninds.nih.gov]

  • Muscular Dystrophy

    This condition is typically characterized by large and abnormally distributed mitochondria on muscle biopsy, which can distinguish this condition from the other muscle conditions[ncbi.nlm.nih.gov] Distal muscular dystrophies are a group of inherited primary muscle disorders showing progressive weakness and atrophy preferentially in the hands, forearm, lower legs, or[ncbi.nlm.nih.gov] Under the microscope, the muscle of a positive biopsy generally shows dead tissue and abnormally large muscle fibers.[cedars-sinai.edu]

  • Primary Lateral Sclerosis

    Muscle histology Deltoid muscle biopsies showed no mitochondrial abnormalities or dysfunction (Table 4 ). Muscle biopsies were normal in seven patients.[academic.oup.com] This locus had not been implicated in ALS or in hereditary spastic parapareses, spinal muscular atrophy, or spinal and bulbar muscular atrophy.

  • Amyotrophic Lateral Sclerosis

    Only about 10% of ALS patients have abnormal nerve conduction study results, but the test can also suggest other diagnoses. A muscle biopsy.[webmd.com] The patients were a 54-year-old man with progressive muscular atrophy who underwent removal of internal fixators in the arm and leg, and a 66-year-old woman with amyotrophic[ncbi.nlm.nih.gov] BACKGROUND: Informal caregivers of patients with Amyotrophic Lateral Sclerosis (ALS) or Progressive Muscular Atrophy (PMA) face stressful demands due to severe impairments[ncbi.nlm.nih.gov]

  • Becker Muscular Dystrophy

    Electromyography was abnormal in all patients. Muscle biopsy in 1 patient demonstrated normal immunostaining for dystrophin.[ncbi.nlm.nih.gov] BACKGROUND/PURPOSE: The purpose of this study was to explore the prevalence, nature and scope of pain in adolescents with spinal muscular atrophy and Duchenne and Becker muscular[ncbi.nlm.nih.gov] Elevated serum CK Skeletal muscle biopsy showing decreased dystrophin quantity Panel overlap The gene on this panel is also included on our Autism Intellectual Disability[unmc.edu]

  • Limb-Girdle Muscular Dystrophy

    Muscle biopsy abnormalities in two individuals very early in the course of their disease suggest that biopsy would probably be useful in detection of preclinical disease in[pediatrics.aappublications.org] atrophy.[ncbi.nlm.nih.gov] Some LGMD subtypes have distinguishing features, including pattern of muscle involvement, cardiac abnormalities, extramuscular involvement, and muscle biopsy findings.[ncbi.nlm.nih.gov]

    Muscle biopsy abnormalities at some time during their disease: i. degeneration and regeneration of muscle fibers ii. necrosis iii. phagocytosis iv. interstitial mononuclear[clinicaltrials.gov] Kennedy disease or X-linked spinobulbar muscular atrophy is a rare X-linked recessive disorder with clinical features of slowly progressive atrophy and weakness of limb and[ncbi.nlm.nih.gov] atrophy).[ncbi.nlm.nih.gov]

    Muscle biopsies showed typical signs of neurogenic damage. Molecular genetic analysis showed mutations of the ASAH1 gene.[ncbi.nlm.nih.gov] […] muscle atrophy survival motor neuron spinal muscular atrophy spinal muscular atrophies of childhood Spinal muscular atrophy Statements spinal-muscular-atrophy-pro Identifiers[wikidata.org] In some situations other tests such as an EMG electromyography (EMG) or muscle biopsy may be needed because it is not possible to conduct the SMN gene tests or no abnormality[genome.gov]
